@f1/VW ATTORNEY BY /WMM Sept. 6, 1938. M. J. DUFFY NONREFILLABLE BOTTLE Filed May 17, 1937 Patented Sept. 6, 1938 i UNITED smrgs errar orgies 1 Claim.

The purpose of this invention is to provide a double neck bottle with means in the neck thereof, which prevents refilling thereof, and which, at the same time, may be formed without enlarging or changing the size and appearance of a bottle; or which, wh-en used with relatively small or short bottles, does not appreciably change the size and appearance thereof.

The invention is a combination of sleeves and ball checked valves in the neck of a bottle, through which a fluid may be poured from the bottle, and which, when an attempt is made to pour or force the fluid back into the bottle, forms a check valve.

Attempts have been made to provide nonrellable bottles, but substantially all of these require enlarging the size of the bottle, or iiuids may be forced into the bottle or will even flow into the bottle when the bottle is immersed in the fluid.

The object of the invention is, therefore, to provide means for forming the neck of a bottle, which permits a fluid to be' readily poured from the bottle, but prevents its being relled without adding to the height or size of the bottle neck.

Another object is to provide means for preventing refilling of a bottle, in which all of the parts may be made of glass, or the same material as the bottle.

Another object is to provide means for preventing refilling of a bottle without the use of springs or the like.

Another object is to provide means preventing relling of a bottle, in which all the parts remain stationary on the bottle after being installed.

Another object is to provide means for preventing refilling of a bottle. in which any of the parts cannot be removed without breaking the bottle.

A further object is to provide means for pre-y venting relling of a bottle, in which the internal area of the bottle is not appreciably reduced.

And a still further object is to provide means for preventing refilling of a bottle, which may be incorporated in the normal neck thereof, which is of a simple and economical construction.

With these ends in view the invention embodies an internal sleeve adapted to be tted into the base of the neck of a bottle, another sleeve having a ball forming a check valve therein, and openings in the sides thereof, an outer sleeve forming a cover for the internal parts and also the neck of the bottle, and a ball adapted to be placed on the inside of the bottle.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein;

Figure 1 is a view showing a side elevation of a wine bottle having the device incorporated in the neck thereof.V

Figure 2 is a yvertical cross-section through the neck of the bottle..

Figure 3 is a plan view looking downward upon the upper end'of the device.

Figure 4 isl a sectional plan through the lower part of the device, showing means locking the device on the bottle.

Figure 5 is a view showing the'outer sleeve forming the neck of the bottle and cover.

Figure 6 is a viewv showing the upper internal sleeve.

Figure 7 is a view showing the'lower internal sleeve.

In the drawing the device is shown as it masr be made, wherein numeral! indicates a bottle, numeral 2 the neck of the bottle forming an outer sleeve or cover, numeral 3 the upper internal sleeve, and numeral 4 the lower internal sleeve or bushing.

Y The bottle shown in the drawing is of the type normally used for wine, and the like, however, it will be understood that this device may berincorporated in bottles of any type or design, or in bottles used for any purpose, and the neck and internal parts thereof may be made longer or shorter, or thicker or thinner,'to accommodate substantially any type of bottle, and the device may be provided.v for use with a bottle having the normal screw cap, as shown in Figure 1, or with a cork, as shown in Figure 2, or any closing means may be used in combination with this device.

The bottle is preferably provided with a relatively short, threaded neck 5, having triangularly shaped recesses 6 formed in the threads, and round pins or rollers 1 are placed in these recesses, and it will be noted that these rollers, installed in this manner, permit the cap 2 to be screwed on the threaded neck 5, however, the rollers l instantly move against the beveled surfaces of the recesses and bind, and, therefore, positively prevent turning the cap or neck in the opposite direction, so that, once the neck is in place, it will be absolutely impossible to remove it without breaking the neck or bottle.

The neck 5 is shown with relatively rounded threads 8, and the cap 2 is correspondingly threaded, however, it will be understood that threads of any type or design may be used. The bushing 4 is placed in the neck 5, and this bushing is formed with an upper valve seat 9, and

a lower valve seat I0, with a communicating passage Il extending therethrough, and with a recess I2 at the upper end adapted to receive the sleeve 3 which is freely mounted therein, and it will be noted that normally a ball I3 will rest upon the valve seat 9, forming a valve to prevent a fluid being poured into the bottle from the upper end, and when the bottle is inverted, a ball I4, indicated by the dotted lines in Figure 2, rests upon the seat I0, forming a. valve, and prevents liquid rising into the bottle, the weight of the ball being suiiicient to compensate for the normal pressure of fluid in an open container, in which the bottle may be immersed.

The ball I4 normally rests in the bottom of the bottle, and, when pouring a fluid from the bottle, it may roll down the side thereof, and against the surface I5 at the bottom of the neck, so that it will not prevent pouring liquid from the bottle unless the bottle is inverted to substantially a vertical position.

The sleeve 3, which rests freely in the recess I2 of the bushing 4, is formed with openings I6 in the sides, and the upper end I'I is closed. This sleeve is held in place by projections I8 extending internally from the cap 2, and above the projections is a cylindrical part I9, into which a cord 20 may be inserted, however, it will also be understood that this section of the cap may be threaded so that a closure may be screwed thereon, as indicated by the numeral 2| shown in Figure 1. This part may be also shaped to accommodate a closure of any type or design.

It will be understood that other changes may be made without departing from the spirit of the invention. One of said changes may be in the use of other means for securing any of the parts together, another may be in the use of other means for holding the balls forming the check valves, and still another may be in the use of other means for permanently locking the cap or neck 2 on the bottle.

The construction will be readily understood from the foregoing description. In use the device may be provided as shown and described, and it will be noted that the bottle will first be filled, the ball I4 placed in the bottle, the bushing 4 placed in the neck, the ball I3 placed on the bushing, a sleeve 3 placed in the upper end of the bushing, and the cap or neck 2 threaded on the neck 5 of the bottle, with the rollers in the recesses in the threaded surfaces thereof. A cork cap or closure may then be applied, and the device is sealed and ready for use.

This bottle will have the appearance of a normal bottle, and the size may or may not be increased, and liquor may be poured from the bottle in the usual manner, however, when an attempt is made to rell the bottle the liquor will be prevented from owing back through the neck.

It will be noted that the only joint in the device that may be considered as exposed is that between the sleeve 2 and the bottle, and this may be sealed by a gasket 22, as shown in Figure 2, if desired. The upper end of the sleeve is sealed by a cork or cap, or any other sealing means may be used.

The interior sleeves in combination with the outer sleeves provide a double neck bottle.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is:

A double neck bottle of the nonrellable type, comprising a bottle, a boss threaded on the outer surface extending from the open end of the bottle, a bushing extending through said boss with sloping valve seats in the opposite ends thereof,Y having a communicating passage between the said valve seats, and positioned with one of said valve seats positioned on the interior of said bottle, a valve closing member positioned on the interior of said bottle and adapted to rest upon the valve seat exposed to the interior of said bottle, said valve member having sufficient weight to preventva fluid passing up through said valve seat with the bottle in the inverted position, a cage with openings in the sides thereof mounted in the'opposite end of said bushing and enclosing the valve seat at the said opposite end, a valve member adapted to engage said valve seat freely positioned in said cage, an outer shell threaded on the said boss extending from the end of the bottle, having closure holding means in the outer end thereof, and having projections extending inward therein positioned to engage and hold the said cage in the said bushing, said threaded boss having triangular shaped recesses therein, and rollers in said recesses permitting screwing of said outer shell on said boss, and preventing unscrewing thereof.
